You are making progress.

Try selecting Step Low Active for your X axis (Motor Outputs) and see if that makes a difference.

Also measure the voltage on your Parallel Port X axis Direction pin (between pin 3 and pin 25) it should change between approx. 0 volts when jogging in one direction and 5 volts when jogging in the other direction. If it only changes between approx. 0 volts and 3.3 volts then that may be the issue.

That would be very useful indeed but I have never heard of any method of importing a Vectric tool table into Mach3.

I think you have to do it the hard way

Hi John,

By trying Fusion 360 doing the tool comp. and the same error persisting has, I think, shown that it is not a Mach3 error.

From the information you have given I would suspect the problem is a mechanical issue with your machine, perhaps backlash, a loose set screw, etc.

Your wiring should be something like this, with the addition of 5Volts supply to the BoB (not sure about using a BEC as I have never tried that).

I never use tool radius compensation within Mach3 (it's easier for me to let the CAD/CAM software take care of this) so my knowledge is limited.


First, check that you have your tool table set up correctly then try running your code again but first change the G40.1 to G40
Does this produce better roundness and dimension ?

Still on about the steppers but I notice that your pdf manual shows two different wire color configurations for the 8 wire motors. It's an off-chance but it may be worth checking (with a multimeter) the resistance of the stepper motor windings just to confirm that you have the correct center taps for the COM connections to the controller.

As you purchased the steppers and controller from the same source and the wires are identified then I am sure you have the wiring correct (sorry but I just had to ask the question).

Please excuse me for asking a really basic question but are you using unipolar stepper motors and have you checked that are they connected correctly ?

G-Code, CAD, and CAM discussions / Re: PROBLEMA WITH G CODE AND MACH3

If you are using Mach3 in Demo Mode (Unlicensed) then it will only display the first 500 lines of Gcode.
Purchasing a license resolves this issue http://www.machsupport.com/shop/mach3/

FAQs / Re: Windows 7 and Mach 3

« on: December 14, 2016, 02:15:19 AM »

Just a couple of things to try...

Check that the Mach3 port#1 address matches that shown in Windows Device Manager for the LPT port. Also check that it is enabled in Mach3.
Run DriverTest.exe (Mach3 folder) just to make sure that the drivers are loaded ok.
